Title: Bobbin thread pull-off for sewing machines
IPC: D05B57/26
Filed: 1964-05-11
Abstract: 1,006,150. Sewing machines. SINGER CO. May 11, 1964 [May 14, 1963], No. 19502/64. Heading D1G. In a lockstitch sewing machine comprising a rotary looptaker, rotation of the bobbin is frictionally braked to impart tension to the thread drawn therefrom, and a bobbin thread pull-off device, arranged adjacent the feed bar, is actuated by the means for inparting feed lift movement to the feed bar to move in a substantially constant path relatively to the feed bar for drawing from the bobbin once during each needle reciprocation only a portion of the bobbin thread required for the next stitch. A vertical axis rotary hook 17 houses a bobbin case 63 containing a bobbin 72 having an upper flange 71 which is supported by an annular surface 70 on the bobbin case. Flange 71 is pressed against surface 70 by a spring-biased arm 75, pivoted to the bobbin case, for tensioning the bobbin thread. The feed bar 33 is pivoted by a bolt 34 to a crank 35 on a feed advance shaft 36. An arm 43 depending from the feed bar is connected by a pivotal link 44 to a crank 45 on a feed lift shaft 46. A feed dog 32 is fixed to a rectangular boss 93 formed on the feed bar above arm 43. A bobbin thread pull-off member 90 has an upper flange 91 which is supported by the feed bar, and is formed with a slot slidably embracing boss 93. A slot 98 in member 90 embraces bolt 34. An arm 96 depending from member 90 is connected by a pivotal link 99 to a crank 102 on the feed lift shaft 46. Member 90 thereby rises and falls with the feed bar, and has reciprocating movement of constant amplitude. Thread from the bobbin passes beneath a rib 28 on the bobbin case, over an inclined surface 79 on the latter, and through an aperture 94 in member 90. The arrangement is such that as the needle and feed dog commences to descend, member 90 is shifted to the left to pull from the bobbin a length of thread somewhat less than the amount required for the smallest stitch.

Abstract: 208,115. Schnetzer, K. Dec. 7, 1922, [Convention date]. Incrustation and corrosion, preventing.-The formation and adhesion of scale in steam boilers, evaporators, economizers, condensers, water pipes, and hot-water apparatus is prevented by connecting the poles of a source of direct current to opposite points of the boiler shell, the voltage of the source being less than that required for decomposition of the liquid. One or more thermo-couples heated by the boiler may be used to supply the current. Voltages from 0.005 to 0.05 and currents from one micro-ampere to a few milli-amperes are stated to effect the required result. Specification 174,905 is referred to.

A dough cutter comprises a rotating dough feed cylinder 1 and one or more knife blades for cutting dough in one or more corresponding grooves on the cylinder, mounting means retaining the or each blade in a plane through the centre of the cylinder during cutting, first displacement means for moving the or each blade towards the cylinder to sever the dough and second displacement means for pivotally displacing the or each blade out of the cutting plane after severing the dough. In one embodiment (Fig. 1) a telescopic member 22 supports the blade 6 and a cam 14 causes a push rod 7 to reciprocate with the blade 6 in a plane 4, while a second cam 20 causes the rod 7 to pivot on pressure member 22 (see Fig. 3, not shown). Cam 14 is supported on a drive shaft 3 and cam 20 on a shaft 19 both shafts being driven by a chain mechanism (17) (Fig. 4, not shown). In a second embodiment (Fig. 9) blades 30 and 31 are located on a rotatable and reciprocatable shaft 29. A shaft 40 is driven by a chain 44 and push rods 41, 42, eccentrically mounted on dies 38, 39 fixed to shaft 40, cause shaft 29 to reciprocate. A further chain 45 drives member 48, 49 (Fig. 5, not shown) which in turn causes shaft 29 to rotate by means of a gearing mechanism. Shaft 29 is mounted in roller carriers (32) guided in ring segments 35. Carriers (32) are connected by scrapers 33 and 34 which move across and clean the blades as the shaft 29 rotates.

[Also in Division B8] Apparatus for washing a tank 2 has a washing liquid flow path from a reservoir 1, through a shut-off valve 6, a venturi 7 and a pump 8 before entering the tank through sprays 5. When not in operation any liquid that leaks through the valve 6 passes into a branch passage 9, through a one-way valve 12 to a drain 11, During a washing cycle, flow of fluid through the venturi causes a suction in the passage 9 which closes the valve 12 and stops air entering. A suction is also caused in passage 13 which opens a one-way valve 18 so that either a detergent container 14 or a sterilent container 15 can be brought into use, depending on which shut-off valve 16 or 17 is opened. The level of liquid in the reservoir is regulated by a float control 3. A control circuit includes timing means whereby a complete series of operations can be initiated, viz. rinse with water only, wash with water and detergent, final sterilization with water and sterilent.

In the automatic clutch control of the parent Specification, wherein an electromagnetic clutch 97 is energized above engine idling speed by a device 95 producing current dependent on the speed of an engine 94, clutch energization is also effected, for towed starting and engine braking, by an auxiliary device 91 which is driven by the clutch output shaft 98, or, as shown, by the output shaft 92 of a gear-box 93 and accordingly produces current dependent on vehicle speed. The device 95 is driven by worm gearing 100 from the engine shaft 102 and is connected to the battery 104 and the clutch 97 through lines 103, 96 respectively. The auxiliary device 91 comprises a generator, is driven through worm gearing 101, and feeds the clutch 97 via a line 91a and the device 95, or directly through a line 99 shown dotted. The current from the auxiliary device 91 rises gradually from zero speed for smooth clutch engagement during engine braking and towed starting. To initiate engine braking a small clutch energizing current is sufficient to accelerate the engine up to the response speed of the device 95; on the other hand, to tow-start the engine a larger clutch energizing current is required. The output current from the auxiliary device 91 is arranged to remain constant above predetermined speeds to avoid interfering with the control of the device 95, and to meet the different conditions of engine braking and towed starting this constant current is selected by a dashboard switch which varies saturation of the auxiliary device generator, or, by means of diodes, limits the voltage fed from the device 91 to the device 95.
